说明：  ：针对MP3 编码方式和帧结构进行分析，利用帧中的比例因子提出了一种压缩域水印算法。算法通过引入帧变化分析步 骤，很好地实现了水印的自适应嵌入。对于不同的系统要求，还可以通过修改门限信噪比的值SNRlim按需进行水印嵌入，使算法 具有更大灵活性。同时在牺牲一定的嵌入空间前提下，实现了水印信息的自同步。实验表明，对于不同风格的音乐，该水印算法 具有很好的不可听性。(In this paper，the encoding method and the frame structure of MP3 are expounded in detail，a watermark algorithm is proposed based on the scale factor in MP3 frame.By introducing the step of frame altering analysis，the algorithm can realize that watermarks is embedded adaptively.By modifying threshold SNRlim（the ratio of signal to noise），the algorithm can meet different requirements of some system，that is what enable the algorithm to have a bigger flexibility.Based on expense of some embedding positions，the watermark can be embedded with self-synchronization.The experiment results show this algorithm can get a good audio effect with various types of audio.)

说明：  研究了电力电子电路中关键元器件，如电解电容、功率 MOSFET、功率二极管、电感等的失效机理及故障模型，分析了能够表征元器件失效的故障特征参数，并确定特征参数的阈值；通过分析元器件及电路在退化过程中电路各输出参数的变化情况，定义输出电压偏移率作为表征电路性能退化的特征参数。(The failure mechanism and fault model of key components in power electronic circuits, such as electrolytic capacitors, power MOSFETs, power diodes, inductors, etc., are analyzed. The fault characteristic parameters that can characterize component failures are analyzed, and the thresholds of characteristic parameters are determined. The variation of the output parameters of the components during the degradation process of the components and circuits defines the output voltage offset rate as a characteristic parameter that characterizes the degradation of the circuit performance.)
